Revelation 4: "Things Which Must Be Hereafter"

New Testament: Student Study guide, (2003), 166–167

Revelation 4 begins John’s vision of events in the future—“things which must be hereafter” (v. 1). His account of this vision comprises the rest of the book of Revelation. Although it occasionally refers to events that occurred before John lived, the events were shown to better teach what will occur in the future.
In Revelation 4 John described a vision he had of the throne of God. The Prophet Joseph Smith received interpretations of some of the symbols in this chapter (see D&C 77:1–5).
